Comparing changes: https://github.com/smarty-php/smarty/compare/v4.3.1...v4.4.1 It is noticeable that Smarty 4.3.1 does not officially support PHP 8.3. Is only supported with 4.4.0. Remark: During tests with Smarty 4.5.1, it was noticed that the following warning occurs: Deprecated: Using the unregistered function "function_exists" in a template is deprecated and will be removed in a future version. Use Smarty::registerPlugin to explicitly register a custom modifier. As of Smarty 5.X.X, templates must be revised again. The Smarty release 5.0.2 is already officially available. However, integration into FlatPress is not entirely trivial.

Error muting is done because some people implemented custom error_handlers using

https://php.net/set_error_handler and for some reason did not understand the following paragraph:
|
|
|
|
It is important to remember that the standard PHP error handler is completely bypassed for the
|
|
error types specified by error_types unless the callback function returns FALSE.
|
|
error_reporting() settings will have no effect and your error handler will be called regardless -
|
|
however you are still able to read the current value of error_reporting and act appropriately.
|
|
Of particular note is that this value will be 0 if the statement that caused the error was
|
|
prepended by the @ error-control operator.
